Make sure you have the following software before you download RDQLPlus:
- Java 1.4 For Your Platform
RDQLPlus is written in Java and uses capabilities only available in v1.4+. If you don't already have a Java 1.4 Runtime Environment, you can download it from http://java.sun.com/
- GraphViz 1.10 Binaries For Your Platform
RDQLPlus depends on the "dot" program from the GraphViz 1.10 distribution. When RDQLPlus runs for the first time, it may prompt you for the full path to the "dot" executable. If you can't provide that, RDQLPlus won't run.
Note: This entire website (including documentation) comes with the download. In the binary release it's in the "website" subdirectory. In the source release it's in the "src/website" subdirectory.
If you're using RDQLPlus for the first time, you should check out the documentation page.
